Try undressing slowly in front of your partner, unveiling your body bit by bit.
If you’re the type that undresses in the bathroom before you have sex to make sure your clothes are folded neatly before attending to other things, forget your tidy (but very unglamorous) tendencies and leave it till the morning (or the afternoon, hopefully).
Try wearing a blouse you can unbutton slowly, revealing your décolleté bit by bit, whilst kissing his neck to get him really turned on.
